[cpreefguy]

I got a few of these kits and theyre pretty cool! They take a Maxi-Jet 1200 from ~300gph and turn it into an ~1800gph monster! Check it out:

How much, and were do you get them...?

[MIOR6485]

Now that is cool and as long as it is cheaper than a tunze its worth it.

Where did you find?

[don-n-sa]

I want two...three if they are a decent price...you selling??????

can you get more?

[dwdenny]

there is a big mod on RC on this exact thing. http://www.reefcentral.com/forums/showthread.php?s=&threadid=790770 this is it split but has a ton of information this this. Plus I like the MJ900 better it only uses 8.5w vs. 20w on the 1200 900 is 230 and the 1200 is 295. still no bad but oh well. Let us know where you got it would like to know the price as well.

A guy on RC was selling them, but has since been banned for selling w/o being a sponsor.
He is setting up a website, www.tritonaquatics.com
He is actually putting alot of research into the kits and is updating his production techniques so Im not sure on the price for the newer kits, I'll shoot him an email to see if he has a set price. I think the new kits are going to be around $50, but well worth it IMO. I'll update the thread when I get a response...

[longhorn_20m]

What is the overall dimensions after the mod? Is it bigger than the original tunze? Has the flow been tested?

[cpreefguy]

The guard that sticks out is about 3" long to give you an idea of the dimentions.
From what I understand the flow has been tested, but I'll get a confirmation.

[longhorn_20m]

so really not much larger than a Tunze, the holder is what makes it look long with the reach it has. Really neat, I want to try these out, get us the hook up!

[cpreefguy]

Im working on it ;)

[dwdenny]

you can build it for $15. but if it comes with that haging bracket I would pay $50

[hammondegge]

nice work, i am interested too.

[falcondob]

I would also be interested in them.
Thanks.

[cpreefguy]

Yeah, it comes with the bracked, GOOD suction cups, everything needed. and it looks slick.

[blueboy]

Yeah, it comes with the bracked, GOOD suction cups, everything needed. and it looks slick.
yeah, i'd say that's worth it, it would take me quite awhile to make one of those DIYs look like anything i want in my tank. perhaps a group buy is in order?

My thoughts exactly :)
Im trying for a G.O. as we speak ^_^

[blueboy]

sweeeet

[hammondegge]

group buy :w00t

[Bug_Power]

anyone with some injection molding experiance can build one! The bracket does look good, but I can mod my bracket to look WAY less intrusive. Maybe even look like a rock. Just buy you a propeller from Tower Hobby $2-4 a black PVC 1.5"x3" long and some hard tubing. Total cost is under $15 and if you make additional they will be even cheaper. I got the parts to make mine but I am waiting on the propellers from tower hobby to arrive. Not a bad mod. I got 2 1200's last week and the flow just from them in my 180 isn't bad. Can't wait for the mods, I may just have to run one! I was thinking about enclosing the MJ in foam and coating it with a light skim of Crete with only the outlet hanging out. You could actually make a fake looking rock out of silicone and aragonite then hide it in your rock work. I'm still debating on how I want to mount mine.

[dwdenny]

I was thinking about doing one my self. I was hoping I could find the CF rods here locally and the props as well but looks like I am stuck with tower hobbys myself. If the group order looks good I will be in for at least one for MJ900

[BIGBIRD123]

Sean,
You do a group order, I'M in for at least two (2).

Steve

[cpreefguy]

the email I got from him:
Right now the kits are not available anywhere. The nylon kits as I've
mentioned in the past are almost finished and I'm really really hoping
to hear news this week that they are at the injection molder being
pumped out in volume.

Kits will no-longer be available through me directly. Because of the
array of products I have lined up I decided to simply become a
manufacturer of my products.

I've got some stores in various parts of the country who want to carry
the kits local and there are some online stores who will be carrying the
products as well. www.saltycritter.com is my primary distributor.

The kits will cost $49.95 ea. - I will be working with the Salty
Critter to offer club members group buys. That price is not yet
determined.

I will also be looking for a retailer in your area to carry the kits so
that they will be available local to you.

Warranty and support on these will go through me and not the stores
carrying the products. If there are problems you will be able to post on
the forums or contact me directly.

If anyone has questions in regards to the kits have them email me at
support@tritonaquatics.com

[dwdenny]

sounds good, seems to have his stuff in order. Let hope that we can get a good group buy together and make it a little cheaper.

[BIGBIRD123]

Sean,
Any word about a group order?

Steve

[cpreefguy]

He is going through a distributor, so no group orders as of now...

[Bug_Power]

are youmaking brackets as well for mounting. I'd gladly mod a 1200 for my LFS so they can see the difference!

[z28pwr]

I'm interested but would like them to increase the cord length. Currently the MaxiJet has a cordlength of 5FT in my 3FT deep tank that doesn't give me enough cord to plug in the powerhead. Hopefully he will extend the cord to atleast 8FT. All the large Tunze pumps come with a 15FT cord.

[dark8nge1]

I'd be in on a group order for a couple

[Darth-Tater]

What about a group order for all of the parts from hoppytower for the parts. Then get together and make the mods in a diy workshop? seems like this would be a heck of a way for MAASTARDS & anyone else to learn something good. Any thoughts on the idea?

David

[TroyPham]

that's a good idea David.

[Bug_Power]

I've made 2 so far and can help out anyway you guys want. I've got a bit of CF rod left, and I can pick up some more ultralight wheels. The CF rod will PROBABLY make 5 or 6 MJ'1200's. Props and such are already soooo cheap I don't think they'll do a group buy. MJ's would be really the only thing I think you could get a deal on. I have seen MJ1200x4 packs on ebay quite cheap.

[jroescher]

I can pick up some more ultralight wheels.


I guess I missed something somewhere. What are these?

I've made a couple of these myself. They really aren't that hard, but I'm hung up on a good mounting option.

[Darth-Tater]

did you buy the stuff local? if not where then. Do you have part #'s Reef central thread is so scattered It is not clear. Maybe a group buy is good, but a group building session sounds super to me. Just a thought

David

[Darth-Tater]

I am trhinking about ordering the parts from hobbytower.com. Anybody interested in any parts? We could split the parts and shipping then get together somewhere ( my classroom after school one day) or anywhere else and attempt this mod. Just a thought. If not I guess I will be forced to go visit my little sister (50yrs old) :innocent in corpus and buy bug power lunch beer etc what ever it takes to show me how to do this. :lol
Any takers on parts?

David

[ou812pezz]

when you ordering? I might be interested in going in halves on the CFR and picking up a couple of props. I was at Lowes the other day pricing the pipe. I think it was $7.95 for a 8' section(the grey kind). I planed on cutting the sections, slots and lip on my table saw with a couple of jigs. LMK

[Darth-Tater]

Thinking about this week probably by Friday. I thought that I would order the rod, 8 props and the glue from them Props where $1.05 each and the mod takes two. The rod is $6.95 for 2 24" pieces and the glue is $6.95 8 props the rod and glue came to $20.00 plus shipping. Think about it.

david

[ou812pezz]

Are you making 4 mods? Wich MJ are you using? I'm thinking of doing a MJ900 . I haven't got to the end of the thread yet. There's like 40 posts. I'll let you know.

[Bug_Power]

I can pick up some more ultralight wheels.


I guess I missed something somewhere. What are these?

I've made a couple of these myself. They really aren't that hard, but I'm hung up on a good mounting option.

The Ultralight wheels fit the 1200's mod. They 1200 mod uses the larger 2" coupleing vs the 2" pipe. On RC I posted that these wheels fit the end of the coupleing great. Just drill out the center so it accepts the CF rod and you can easily center the prop. These wheels were found at an RC shop here in Corpus and are basically plastic wheels with a very small hub which doesn't limit flow
check here for what I'm talking about...

[Darth-Tater]

No only going to do two. I figured that someone would like the other four. If not they are so cheap that if no one wanted to join me I would just keep em

David

[ou812pezz]

I could split the 20 plus shipping. Are you getting the 1.75 Dumas props? Which MJ are you modding?

[Darth-Tater]

The mods list on Reef Central said this prop
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXE471&P=7

Maybe the mod is more trouble than it is worth.


DT

[ou812pezz]

I have a shop of tools. I found a store on Fredricksberg rd that carries the rods. She can also order props. I'm going to call her tomorrow with the parts numbers and see what prices are. No shipping costs. I'll let you know tomorrow evening.

[longhorn_20m]

Has anyone successfully completed this mod?

[Darth-Tater]

ou812pezz (patrick) has been working on it. We talked last night and have ordered the parts here in SA. prototype is almost read he said. He has done an awesome job of working on it.

DT

[Bug_Power]

i've got 2 1200's running in my 180 now!

[mathias]

who wants to make me one :)

[Sherri]

I'm interested too... :)

[Sherri]

i've got 2 1200's running in my 180 now!

me also....

[longhorn_20m]

I would like two for the Maxijet 900. Can someone help?

[Bug_Power]

Sherri, it's alot of flow isn't it for two 17 watt pumps!

[mathias]

I would pay someone to make me 2 of these.....

[Bug_Power]

What size do you want? If you need 1200's I can make you some.

[mathias]

yea 1200

[longhorn_20m]

How much for 1200s?

[Bug_Power]

Parts run about $10 or so....then what ever you feel my time is worth. I won't paint them because, honestly I don't know how I passed art class! So it would be shipped in PVC white. You'll want to color it up though. I painted one and left one white...white defintaly looks dingy after a while.

[mathias]

ok... give me a price for two... lets rolllllllllllllll

[Bug_Power]

How does $40 for two sound?

[cpreefguy]

How does $40 for two sound?
Pretty reasonable to me!

[brewercm]

I must have missed this thread for a while. If anyone is still working on getting these PM me. I'd be interested in getting two for my maxijet 1200s I have running.

Thanks

[mathias]

yea $40 sounds great.... let me know when I can pick them up :)

[Bug_Power]

I would need you guys to mail me your magnet and impellors. They have to be modded so the prop stays on. I have 2 props here already for 1200's with single 1.75" props. If you guys want I can send just a big parts kit that you glue together if you can't have me do it. It's not that hard to put together, you just have to have a chopsaw or a drill to cut the slits in the PVC.

[mathias]

I was hoping you have everything and ship it all to me.... Ill send you the funds through paypal..... with my mailing info..... just noticed your in corpus... but still interested...

[Jimnorris]

If I ship you two maxijets would you do two for me?
Thanks,
Jim

[hammondegge]

Hey Bug, i too would love two.
robert

[ou812pezz]

I am actually throwing a few of these together. I can cut the housings. I've have 3" and 2" 1 1/2" housings ready to mount for the 1.25" props. All parts bought locally(props,tubing,CFR,AL). I've successfully completed one mj 1200 WITH DUAL 1.25" NITRO PROPS. Throws a wide flow. I am upgrading to 1.75 prop for wide and long dispersion. It's an easy mod. I must warn though that the Mj 1200 makes a noticable hum as reported in the RC thread. I'm not interested in taking any business away from Bug but if you're doing it yourself and need a helping hand just hollar. Hey bug are you using the 1 1/2" coupler for the the housing on the 1.75" prop?

[Bug_Power]

Yeah basically it's a RC Ultralight wheel on the end 1.5" coupler, some 1.5" pipe and a 1.5" test cap. The impellor is a 1.75" dumas with hard tubing connected to it, then flexible airline connecting the prop to the MJ impellor magnet. The shaft is .98 CF rod with the endcaps of the original MJ on it.

[mathias]

see all that you said.. just proves it more that you can make me two and mail them and Im willing to pay :)

[Bug_Power]

lol...I'll contact each of you as I get time. I don't want 10 people sending me units that i can't mod and get out quickly. So I'll go down and get to you guys one at a time.

[ou812pezz]

Where do you get the RC Ultralight wheel from? I assume this replaces the center brace.

[Bug_Power]

Hobbie shops...I don't have any left over I'm going to have to get some more from the hobby store. If you look at the RC thread, I listed a link to what it was.

[ou812pezz]

is the 38mm RC light wheel? I just found the secound article and briefly skimmed it.

[Bug_Power]

I think so....basically if fits JUST on the rim of the coupling. Guys keep an eye on ebay and buy the 4 packs of MJ1200's you can get a pretty good deal that way. Unfortunatly I don't want to buy them myself. You can buy them and have them shipped to my address.

[ou812pezz]

I've completed 3 of these mods and finishing a fourth. Two MJ 1200's and 2 MJ 900's. Most of the parts like the prop, carbon fiber rod(2.5 mm X 610mm $6.49)(or stainless steel rod), ultra light wheel(1H01/51 2" GWSQ2205 $1.25) and carbon fiber tube can be purchased loacally at The Hobby Center on Frericksberg road(no shipping). The rest can be purchased at Lowes( test cap, PVC pipe and 1-1/2"coupling)and LFS(rigid tubing, airline tubing). With the MJ 900, I find a dual nitro hammer prop( HCAB 7750 $4.99 comes with 2 props) works best. It's quiet and throws a wide stream. Draw back is you have to drill out the center to fit the 3/16" tube. If you use the MJ 1200, I found the Dumas 1-3/4" prop(NO.3004 $1.25 per prop) throws the best stream. No drilling required. draw back is that it hums. Well if there are any questions just holler

[hammondegge]

found this today http://www.mjmods.com/index.php?main_page=index

[TruonkQ]

hehe i made two my self, but it doesn't push out as much as i wanted it to. Works great in small tanks such as 90g or smaller. It pushes more water than a mj1200 though, but not 1800gph. Maybe it just need a better prop.
